aglK

Alpha-glucoside transport ATP-binding protein AglK

362 amino acids

Part of the binding-protein-dependent transport system for alpha-glucosides such as sucrose, maltose and trehalose. Probably responsible for energy coupling to the transport system.

Belongs to the ABC transporter superfamily.

aglK

UDP-N-acetylglucosamine--dolichyl-phosphate N-acetylglucosaminyltransferase

251 amino acids

Involved in the assembly of an N-linked disaccharide that decorates the S-layer glycoprotein and flagellins (PubMed:18978056). AglK initiates N-linked glycosylation through the formation of alpha-linked dolichyl monophosphate N-acetylglucosamine. It catalyzes the transfer of GlcNAc from the donor substrate UDP-GlcNAc to dolichyl phosphate C55 (Dol-P) to yield Dol-P-GlcNAc (PubMed:23624439). AglK reaction proceeds with retention of stereochemistry (PubMed:23624439). The reaction is specific for UDP-GlcNAc. AglK shows a stronger preference for short dolichol (C55-60 Dol-P) substrates compared with the longer (C85-105 Dol-P) (PubMed:23624439).

Belongs to the glycosyltransferase 2 family.
